I dont know what Zaela means, atleast not enough that i will try and explain it, but i know what i mean.
My Shaman always uses the Murk spell, Bear form with some hp and awesome proc, love that spell. But it makes him look like a bear, i hate that. So what i was able to do, is click on Illusion Gender, and click it off, then he would look like an Iksar again, and still have the benefits of the Bear illusion, yay!
I do the same with my Monk and Paladin, if i click on Frog or Fire Illusion, i always click on Gender Illusion, click Gender off, and once again i look like Iksar or Erudite and still have the benefits of Frog/Fire.
Im not 100% sure what Zaela means, but i dont think it means "sure man, we will fix it right back to how you liked it". (Sadly, for me, and for you to listen to my crying about it).
